IOWA c ROLL SCREEN INSTALLATION FOR CASEMENT WINDOWS Application filed May 13, 1929.

The object of my invention is to provide "a roll screen installation preferably adapted for use in connection with steel casement windows.

More particularly, it is my object to provide a means for mounting the guide tracks of the roll screen and the roll screen itself upon the casement window frame in such manner as will allow for easy adjustment of the roll screen assembly on the frame.

It may be here mentioned that in setting casement frames, it readily follows that the sill adjacent the window frame varies in position relative to the lower rail of the casement frame.

In some types of steel casement windows there is provided a movable portion, whereby the window may be open and still other portions of the window which are permanently closed.

Due to the fact that the sills may vary somewhat in position and due to the fact further, that the roll screen assembly is to be mounted on a. permanent part of the frame, there often occurs the necessity of adjustment so that when the roll screen is withdrawn, the lower edges of the track will rest upon the sill of the window opening.

It follows that the screen is not always positioned in exactly the same location rela- "tive to the window frame and therefore, it is desirable to provide a mounting wherein adjustment may be readily had and wherein the entire roll screen assembly may be quickly and easily mounted on the window frame and detachably held thereto.

Still a further object is to provide headed studs on the window frame which are adapted to coact with key hole slots formed in the track mounting for the roll screen.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 2 is a. horizontal sectional View taken on line 2-2 of Figure 1.

Figure 3 is a detail sectional view taken on line '33 of Figure l.

Figure 4 is a perspective view of one end of the roll screen casing and receiving memher for receiving such end.

Figure 5 is a perspective view of the receiving member, illustrating the key hole slot. v

Figure 6 is a perspective view of the channel-shaped filler member.

Figure 7 is a horizontal sectional view takso that there is no movement of them. The

window frame also includes a pair of movable window sections 16. The window section 16 is defined by a pair of vertical frame elements 18 and a cross or horizontal frame element 20. a

In order to screen the open. portion of the window it is necessary to mount the roll screen casing in position so that it rests in alignment with the cross frame 20 and the tracks thereof rest against the vertical frame elements 18, all as clearly illustrated in Figure 1 of the drawings.

It will be noted that the usual casement window is of the out-swinging type and that my roll screen is mounted on the inside of the house or building and neatness in appearance is an essential necessity.

A window sill 22 is positioned against the lower rail or frame 24 of the window frame 12. When the building is built, the window frame 12 is positioned within the rough window opening and in many cases when the sill is placed in position, it varies in height relative to the lower rail 24 of the window frame 12, for example, in some instances, the upper edge of the lower rail 24 may project an inch above the sill 22, while in other cases in the same building where the same type of casement window is used, the sill may be positioned only one-half inch below the upper edge of the rail.

In order to screen all of these windows and have the screen rest against the sill 22 it is essential that adjustment be had, which adjustment does not in any way interfere with installation nor neatness of appearance.

The particular method of installation which I have devised will hereinafter be more fully set forth.

A roll screen casing 26 rectangular in cross section is provided that carries a spring roller assembly 28. Flexible screen 30 is adapted to be wound on the roller assembly 28 or to be unwound therefrom.

The side edges of the screen 30 are adapted to travel in guide tracks 32. It is necessary that the screen be spaced inwardly approximately two or two and one-half inches from the surface of the window itself so as to take care of any handles or other windowhard- .flange'40 of the track or guide 32 is adapted to project. The flat flange is frictionally held between one wall of the receiving member 34 and one wall of the filler member 36, as clearly illustrated in Figure 7 of the drawings.

It will be noted that the side edges of the screen are spaced inwardly a considerable distance from the normal window jambs formed on the wall 10. The coacting members 34 and 36 provide the necessary mounting and retaining means for holding the guide tracks 32 in proper position.

In order to mount the coacting members 34 and 36 upon the frame 12, I provide headed studs 42, which may be riveted or otherwise secured to the frame elements 18 of the window frame 12; The headed studs are adapted to project through key hole slots 44 formed in one wall of the receiving member 34. The key hole slots 44 are vertically arranged and are inverted from the position of a normal key .hole slot.

By providing a plurality of vertically spaced headed studs 42 on the frame 18, I am able to mount and connect the receiving members 34 to the frame elements 18.

In order to positively lock the receiving members 34, I employ a cam shoe 46, which is adapted to slip over the head of the stud 42, as clearly illustrated in Figure 8. This arrangement positively locks the receiving member 34 to the frame element 18.

It will be noted that the elongated key slot 44 allows for vertical adjustment of the receiving member 34 relative to the frame element 13. It thus follows that when the sill 22 varies in position relative to the frame 12, such variations may be compensated for by adjustment of the receiving member 34. The receiving member 34 may always be positioned so that it rests on the upper surface of the sill 22.

The headed studs are permanently located in the frame 18. In some instances, screws may be provided in place of headed studs 42. In the case of screws, after the receiving members 34 are in position they can be tightened and in this way, the receiving members will be securely held in position.

By providing the elongated key hole slot I am able to take care of any necessary adjustment and at the same time have either the headed studs 42 or screws placed upon the frame at the factory, which is a very important feature in proper installation of rolling window screens.

The upper end of thereceiving member 34 is closed with an end piece 48. The filler block, which is channel-shaped in cross section, is shorter than the receiving member 34 and thus a pocket A is provided for receiv ing one end of the screen casing 26. The

vertical position of the casing 26 is entirely dependent upon the receiving member 34 and its position.

Thescreen normally mounted within the casing 24 is adapted to travel in the guides 32, which are held in position between the coacting members 34 and 36.

It will be noted that when it is desired to disassemble and remove the roll screen from the window frame it can easily be accomplished by first removing the filler members 36 and thereafter the tracks 32. The screen casing 26 may then be withdrawn from its position and only the receiving members 34 left secured to the frame 12.

The receiving members may likewise be removed by simply withdrawing the cam locking elements 46.. In many instances, it is not necessary to use cam locking elements 46 and by properly spacing the head of the stud away from the frame element 18, thus the thickness of the material of the receiving member 34 will fit therebetween.

It will be further noted that the enlarged portion of the key hole slot is large enough to slip over the heads of the studs 42 and thereafter by moving the receiving members 84 downwardly, the same will be retained in position relative to the frame element- 18.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included Within their scope.

I claim as my invention 1.
